What is the difference between an electric drill, a percussion drill, and an electric hammer

1.Different nature.

Electric hammer: An electric hammer is an electric rotary hammer drill with a safety clutch with a pneumatic hammer mechanism.

Percussion drills: Percussion drills work by rotating and percussion. A single impact is slight, but a frequency of more than 40,000 impacts per minute can generate sustained force. Can be used on natural stone or concrete.

2.The principle is different.

Electric hammer: The principle of electric hammer is that the transmission mechanism drives the drill bit to rotate, and at the same time there is a reciprocating hammering motion perpendicular to the rotating head. The electric hammer is to drive the piston through the transmission mechanism to compress the air in the cylinder, and the periodic change of the air pressure in the cylinder drives the hammer in the cylinder to hit the top of the brick back and forth, just like we use the hammer to smash the brick, hence the name electric hammer.

Percussion drill: When the percussion drill is working, there is an adjustment knob at the drill chuck, and there are two adjustment methods: ordinary hand drill and percussion drill. The impact drill uses the gears on the inner shaft to knock each other to achieve the effect of impact, and the impact force is much less than that of the electric hammer. It is not suitable for drilling holes in reinforced concrete.

3.Different uses.

Electric hammer: Electric hammer is a type of electric drill, which is mainly used to drill holes in concrete, floor, brick wall, and stone. Professional wall, concrete, stone drilling, and multi-functional electric hammers, as long as they are adjusted to the right position and matched with the right drill bit, can be used instead of ordinary electric drills and electric picks.

It has the advantages of high efficiency, large hole diameter and long drilling depth.

Percussion drill: mainly used for percussion drills for concrete floors, walls, bricks, stones, wood boards, and multi-layer materials; In addition, it can drill holes and tap teeth in wood, metal, ceramic and plastic, and is equipped with electronic speed control equipment for forward and reverse rotation and other functions.

Precautions for percussion drilling:

In general, percussion drills cannot be used as electric drills:

1.Because the direction of the percussion drill is not easy to grasp when it is used, it is easy to misoperate and the hole opening is too large;

2.The drill bit is not sharp, so that the hole is not neat, burrs or cracks appear;

3.Even if there is a transfer switch on it, try not to use it to drill holes. Unless a special drill bit for drilling wood is used, due to the fast speed of the drill bit, it is easy to make the hole black, and the drill hair is hot, which affects the service life of the drill bit.

Percussion drills are a little slower to drill walls, they can't penetrate walls, but they are better than electric hammers when striking iron and wood. Percussion drills are suitable for use on stones and concrete, and can be rotated or impacted. The electric hammer relies on rotation and hammering to work.

And its individual hammering power is also very high. Compared with the hammer drill, it uses the least pressure to drill into some hard materials, and it has a cylinder, while the hammer drill does not. If you want to make holes in the wall, it is better to use an electric hammer.

An electric hammer can be used as a chisel and only does hammering work, whereas a percussion drill is impactful and can be used as an electric drill. Percussion drills are mainly rotating, with slight vibration, and can only be drilled in easy places, such as brick walls, while electric hammers have strong vibrations and can be used on cement walls. The volume, weight and power of an electric hammer are greater than that of a percussion drill.

Electric drill: Under the impact force comparison, you can generally make some small holes, or you can tighten the screws, and the range of use is relatively wide.

Percussion drill: used for punching large holes, suitable for drilling holes in concrete walls.

Electric hammer: A breaking tool that can be used to knock out some areas that are considered redundant, and are basically used on walls.

First, the principle is different.

1. Electric hammer: The electric hammer is the use of the principle of piston movement, compressed gas impact drill bit, does not need much strength by hand, can open 6 100mm holes in concrete, bricks, stones and other hard materials.

2. Percussion drill: mainly rotary cutting, and an impact mechanism that relies on the operator's thrust to produce impact force.

Second, the use is different.

1. Electric hammer: The electric hammer is mainly used to drill holes in concrete, floors, brick walls and stone. Specializing in the wall, concrete, stone on the hole, there is also a multi-functional electric hammer, adjusted to the appropriate position with the appropriate drill bit can be used instead of ordinary electric drills and electric picks.

2. Percussion drill: an electric tool used for drilling holes in bricks, blocks and lightweight walls.

Third, the characteristics are different.

1. Electric hammer: a good shock absorption system can make the operator comfortable to hold and relieve fatigue; The precise speed control switch, with a low speed when the switch is lightly touched, can help the machine to start drilling smoothly (e.g. drilling on smooth surfaces such as tiles, which not only prevents the drill bit from slipping, but also prevents the drill hole from breaking. High speed can be used to ensure work efficiency during normal operation.

2. Impact drill: The motor voltage of the impact drill has two different voltages of 0V-230V and 0V-115V, which controls the clutch of the micro switch, obtains the speed of the motor and obtains the speed of the motor.

1. The nature is different

Electric hammer: The electric hammer is an electric rotary hammer drill with a safety clutch with a pneumatic hammering mechanism.

Percussion drills: Percussion drills rely on rotation and percussion to work. A single impact is very slight, but a frequency of more than 40,000 shocks per minute produces a continuous force. Can be used on natural stone or concrete.

2. The principle is different

Electric hammer: The principle of electric hammer is that the transmission mechanism drives the drill bit to do rotational motion, and at the same time, there is a reciprocating hammering motion in a direction perpendicular to the rotor. The electric hammer is driven by the transmission mechanism to drive the piston to reciprocate the compressed air in a cylinder, and the periodic change of air pressure in the cylinder drives the hammer in the cylinder to reciprocate and hit the top of the brick, as if we use a hammer to hit the brick, hence the name electric hammer.

Percussion drill: There is an adjustment knob at the drill bit chuck when the percussion drill is working, and there are two ways to adjust the ordinary hand drill and the percussion drill. However, the impact drill uses the gears on the inner shaft to jump out of each other to achieve the impact effect, and the impact force is far less than that of the electric hammer. It is not suitable for drilling reinforced concrete.

3. Different uses

Electric hammer: Electric hammer is a type of electric drill, which is mainly used to drill holes in concrete, floor slabs, brick walls and stone. Specializing in wall, concrete, stone punching, as well as multi-functional electric hammer, adjusted to the appropriate position with the appropriate drill bit can replace the ordinary electric drill, electric pickaxe use.

The advantages are high efficiency, large hole diameter and long drilling depth.

Percussion drill: mainly suitable for percussion drilling on concrete floors, walls, bricks, stones, wood boards and multi-layer materials; In addition, it can also drill and tap on wood, metal, ceramic and plastic, and is equipped with electronic speed control equipment for reverse and other functions.

Precautions for percussion drills:

Percussion drills generally cannot be used as electric drills

1. Because the direction of the percussion drill is not easy to grasp when in use, it is easy to misoperate, and the opening is too large;

2. The drill bit is not sharp, so that the hole is not neat, and burrs or cracks appear;

3. Even if there is a transfer switch on it, try not to use it for drilling, unless you use a special drill bit for drilling wood, but because the speed of the electric drill is very fast, it is easy to make the opening black and make the drill hot, thus affecting the service life of the drill bit.

1. The difference between percussion drill and electric hammer:

1. In addition to drilling metal and wood, the percussion drill can run drilling operations on brick walls and ordinary concrete, but if it is pouring reinforced concrete, the percussion drill will be more laborious to drill, and the percussion drill cannot penetrate the wall (because the percussion drill relies on two impact gears to impact each other, and the percussion drill must be selected for the working face with tiles.)

2. The electric hammer is the impact of the cylinder piston movement, so the impact force of the electric hammer is much greater than that of the ordinary impact drill) If you want to drill in a relatively hard concrete, the drilling efficiency is high. Or run drilling operations in concrete for a long time, or if you want to penetrate walls, choose an electric hammer. Choosing an electric hammer to process the tile surface is easy to break the tile.

Second, the percussion drill relies on rotation and impact to operate. A single shock is very slight, but every minute.

More than 40,000 impact frequencies allow continuous force to occur. Percussion drills can be used in natural stone or concrete. The rotary hammer relies on rotation and hammering to operate.

Individual thrashing forces are very high and have a thrashing frequency of 1,000 to 3,000 per minute, significant forces can occur. Compared to percussion drills, electric hammers require minimal pressure to drill into hard materials.

3. In a general sense, the percussion drill is more suitable for home users, and the electric hammer is more suitable for use in work, please refer to the actual standard for details.

Percussion drills rely on rotation and percussion to work. A single impact is very slight, but a frequency of more than 40,000 shocks per minute produces a continuous force. Percussion drills can be used on natural stone or concrete.

Electric hammers rely on rotation and hammering to work. The individual hammering force is very high and has a hammering frequency of 1,000 to 3,000 per minute, which can produce significant force. Compared to percussion drills, electric hammers require minimal pressure to drill into hard materials such as stone and concrete; Especially relatively hard concrete.

Under normal circumstances, the percussion drill cannot be used as an electric drill, because the direction of the percussion drill is not easy to grasp when it is used, and it is easy to misoperate, and the opening is too large; Second, the drill bit is not sharp, so that the hole is not neat, burrs or cracks appear; Third, even if there is a transfer switch on it, try not to use drilling, unless you use a special drill bit for drilling wood, but because the speed of the electric drill is very fast, it is easy to blacken the opening and make the drill hot, thus affecting the service life of the drill bit.

I recommend that you use special carpentry tools.

The electric hammer is generally a hydraulic piston impact, that is, it can hammer the concrete, through the wall to make holes, etc., which is quite violent. Compared with the electric hammer, the function of the impact electric drill is slightly lighter and less vigorous than the electric hammer.
